A prison officer has been sacked and four others disciplined for wearing T-shirts printed with the words 'we have Madeleine McCann I would want to know about this."
The man who was dismissed from his position is said to be a senior member of staff. Another officer is currently suspended and three others received written warnings.
A Ministry of Justice spokesman said: "Appropriate disciplinary action has been taken following an incident concerning a number of prison officers outside of working hours and away from the prison."
The Prison Service added: "An investigation has taken place at HMP Wandsworth and appropriate disciplinary action has been taken following an incident concerning a number of prison officers outside of working hours and away from the prison."
Last month The Sun newspaper apologised after a tweet about Madeleine was sent out during The X Factor. It read: "Forget make up, the only way Tamera's gonna lose this is if she admits to stealing Maddie."
